There is now a dynamic list at [instances.peertu.be](https://instances.peertu.be/instances), maintained by [@Chocobozzz](https://github.com/Chocobozzz). It is not playing any role in the federation process at the moment, but it's a nice aid if you want to discover instances or be discovered.
If you want to follow them automatically as they come you have 2 scripts, but *then beware that you blindly trust every other admin for enforcing sane moderation policy* :
- - [Peetube AutoDiscover](https://github.com/Jorropo/PeerTube-autoDiscover) by Jorropo, that use following and followers list of already to discover new node.
- - Discover all node in the federation (if an admin forgot to their node in list this isn't a problem).
- - Doesn't require a central node exchange point (node list)
- - Much secure than shell script (shell script use file as variable)
- - [script from Skid](https://github.com/Chocobozzz/PeerTube/issues/406#issuecomment-397452809) and [python3 version](https://gist.github.com/Jorropo/e5e7bc471e290cb8098e36b150288631)
- - Lot more faster
- - Protect privacy (maybe if someone haven't list her node on [instances.peertu.be](https://instances.peertu.be/instances) there is a reason)
- - Shell script haven't any problem to solve with tls (with both python version you maybe need to manually solve https problem, depends of dist)

You can do a cron like `*/10 * * * * /opt/peertube-autofollow.py >/dev/null 2>&1` to automate its update.
